US Patent 11390288 Other-vehicle action prediction method and other-vehicle action prediction device

An other-vehicle action prediction method predicts that another vehicle traveling in an adjacent lane adjacent to an own lane in which a host vehicle is traveling makes a lane change from the adjacent lane to the own lane in front of the host vehicle in accordance with the behavior of the other vehicle. The other-vehicle action prediction method acquires traffic regulation information on a traffic regulation regarding the adjacent lane, predicts a predicted traveling state of the other vehicle when traveling according to the traffic regulation, calculates a recognition possibility that the other vehicle recognizes the traffic regulation, and predicts that the other vehicle makes a lane change in accordance with the recognition possibility, the predicted traveling state, and the actual traveling state.
